Precautions/Procedures
)General Precautions
Carefully inspect any SRS part before you install it.
Do not install any part that shows signs of being drop-
ped or improperly handled, such as dents, cracks or
deformation:
- Airbags- Cable reel- SRS unit- Seat belt tensioners
N
)-
Use only a digital multimeter to check the system, lf
it's not a Honda multimeter, make sure its output is
10 mA (0,01 A) or less when switched to the smallest
value in the ohmmeter range. A tester with a higher
output could damage the airbag circuit or cause acci-
dental deployment and possible injury.
Do not install used SRS Dans from another vehicle,
When making SRS repairs, use only new pans.
Except when performing electrical inspections,
always disconnect both the negative cable and posi-
tive cable from the batterv. and wait at least three
minutes before beginning work.
Replacement of the combination light and wiper/
washer switches and cruise control switch can be
done without removing the steering wheel:
- Combination light and wiper/washer switch replace-
ment {see section 231.- Cruise control sevresume switch replacement (see
section 41.
Whenever the ignition switch is ON {ll}, or has been
turned OFF for less than three minutes, be careful not
to bump the SRS unit; the airbags could accidentally
deploy and cause damage or injuries.
Whenever the airbag has been activated, replace the
SRS unit.
The original radio has a coded theft protection circuit.
Be sure to get the customer's code number before dis-
connecting the battery cables.
)
Airbag/Seat Belt Tensioner
Handling and Storage
Do not try to disassemble an airbag or a seat belt ten-
sioner. They have no serviceable parts. Once an airbag
or a seat belt tensioner have been deployed. they cannot
be repaired or reused.
For temporary storage of an airbag or a seat belt ten-
sioner during service, please observe the following pre-
cautons:
. Store the removed airbag with the pad surface up.
The driver's/front passenger's airbag connectors and
seat belt tensioner connectors have a built-in short
contact (see page 24-211.
@ r th€ airb.g is impropcrty stor€d face down,
accidental deployment could propel the unit with enough
forc€ to caus6 serious iniury,
Store the removed on a secure flat surface awav from
any high heat source (exceeding 212"F/100'C) and
free of any oil, grease. detergent or water.
lmproper handling or storage can internally damage
the airbag and seat belt tensioner. making them inop-
erative.
lf you suspect the airbag and seat belt tensioner have
been damaged, install new units and refer to the
Deploymenvoisposal Procedures for disposing of the
damaoed units.

Troubleshooting
Self-diagnostic Procedures
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this informa-
tion in memory, For easier troubleshooting, this data can be retrieved via a data link circuit.
. When you turn the ignition switch ON (ll). the SRS indicator will come on. lf it goes off after six seconds, the system is
normal.
. lf there is 8n abnormality, the system locates and defines the problem. stores this information in memory, and turns
the SRS indicator light on. The data will remain in the memory even when the ignition switch is turned off or if the bat-
terv is disconnected.
. When you connect the SCS service connector to the service check connector (2P), and turn the ignition switch ON (ll),
the SRS indicator light will indicate the diagnostic trouble code (DTC) by the number of blinks.
. After reading and recording the DTC, proceed with the troubleshooting forthis code.
Precsutions
. Use only a digital multimeter to check the system. lf it's not a Honda multimeter. make sure its output is 10 mA (0.01 A)
or less when switched to the smallest value in the ohmmeter range. A tester with a higher output could damage the
airbag circuit or cause accidental airbag deployment and possible injury.
. Whenever the ignition switch isON (ll). or has been turned OFF for less than three minutes, be careful nottobumpthe
SRS unit; the airbags could accidentally deploy and cause damage or injuries.
. Before you remove the SRS main harness, disconnect the airbag and tensioner connectors (see page 24-23).
. Make sure the battery is sufficiently charged (see section 23). lf the battery is dead or low, measuring values won't be
correct.
. Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the terminals
with a jumper wire. Use only the backprobe set and the SCS service connector.
For backprobing spring-loaded lock type con nectors, .efet to page 24-22.
Reading the DTC
When the SRS indicator light is on, read the DTC using one of these methods;
A. Connect the Honda PGM Tester to the 16P Data Link Connector {DLC), and follow the tester's prompts. lf the tester
indicates no DTC, DTC 9-1 and DTC 9-2, double-check by jumping the service check connector (2P) and watching the
SRS indicator light (see next page).
